I have run a number of generators and pumps on veg for years. I have used the Chinese engines both in Vertical and horizontal types. The horizontals are far and away the best and the ones to go for. Lister engines also work well on veg but from what I read on the lister sites, they are hard to come by in the US and subsequently ridiculously priced to what they are obtainable for in the UK and Oz. You may be able to pick up an Indian " Listeroid" clone as a "Compressor" with a parts kit to turn it into an engine to get around your idiotic EPA regs and bans on the import of these engines.

If you are looking to run a small pre-made generator with the Vertical engines, I'd suggest you use 10% ULP and fit it with some sort of Drip type water injection. The old style engines of this type ran well on SVO but I suspect again through EPA stupid regs the injection pressures and maybe compression or timing has been altered and they are now prone to coking up.

Let us know specifically at what you are wanting to do and use and I can give you some more specific answers and possible solutions. There are a lot of possible setups depending on what you want to do. Some people have generators supplying their whole home off grid where they use the bigger Horizontal China Gennys, others use listers, some have them topping up solar systems, some use them for back feeding etc.

great post lots of usefull info!! did you really ask your wife you you could cook with the virgin olive oil HAHA!! I heard of the lister engines not what i'm looking for tough they to be awsome generators.

That looks like a very high quality unit. I'm sure from looking at the specs that engine would do fine on Veg. The compression is much higher than the China Verticals which is what you want.

I am pretty suspect on the stated Fuel consumption of the generator, if that matters in this case. The number they quote would be far more in line with a Hp/ Hr figure rather than the consumption of the machine at full output as the white paper appears to state. I can't see a 7 kilo generator using under 700Ml of fuel an hour. That's way better than Lister territory and I have yet to see any high speed engine go near their economy.

Other than that it looks a nice unit and you would also have the ability to use the coolant water in a co-generation setup to add to the efficiency of the thing. Not cheap unit by any means but as they say, you get what you pay for. Also being a perkins engine you could get spares easily. I think you can still get them for the first motor they ever built.

The alternator is a 10 kilo unit which means it is underrated in this app. That's good as it means the gen head will pull the engine down rather than the engine over drive the alt and burn it out. The engine controller also looks very good and has the ability to drive other accessories. You may be able to rig that up to a valve for start up and shut down on Dino or bio and have the thing change over after it reaches a certain temp or time.

Just looked at the engine data sheet, 2.7L of fuel an hour at full load. Much more like I would expect. Maybe the consumption figure on the generator sheet is a typo.... deliberately or otherwise.

Looks like a very nice unit that would do well on veg. When you getting one??
